Boral Roof Replacement Nationwide

Boral Roof Replacement in Los Angeles: What to Know First

Boral roof replacement in Los Angeles means tearing off a concrete or clay tile roof system and rebuilding it properly, and that work typically runs $18 to $32 per square foot depending on which Boral tile profile you’re matching and what’s underneath. Most full Boral replacements take us five to eight working days once materials are on site, though tile lead times from the manufacturer can add two to four weeks. We’re an independent Boral service provider, not a factory arm, so you get straight pricing on the genuine article or a quality equivalent without the showroom markup.

Call (945) 303-9821

This page is for homeowners whose Boral roof has reached the point where patching no longer makes sense: cracked tiles spreading across multiple slopes, underlayment that’s failed after 20 to 25 years of Los Angeles sun, or leaks that keep coming back no matter how many tiles get swapped. If that’s you, call (945) 303-9821 and we’ll schedule a free inspection and written estimate.

Key Takeaways

• Boral tile roofs in L.A. typically last 40 to 50 years, but the underlayment beneath them fails at the 20 to 25 year mark.
• Replacement cost is driven by tile profile, roof complexity, and what’s under the tile. Most jobs run $18 to $32 per square foot.
• You don’t have to replace every tile. We often reuse 60% to 80% of existing Boral tile and replace the broken ones.
• We quote the full number in writing before a single tile moves. That’s how Greg Holloway runs every Tilehurst job.

How Boral Products Fail - and How We Fix Them

Boral makes a solid tile. The failure we see on Los Angeles roofs is rarely the tile itself failing first. It’s almost always what’s underneath. Here’s what we find when we strip a Boral roof in this city, and what we do about it.

• Boral Barcelona barrel tile with failed 30-lb felt underlayment. The Barcelona profile is everywhere in Los Angeles, especially in hillside neighborhoods built in the 1980s and 1990s. The tile still looks fine from the street, but the felt underneath has baked and torn. On those jobs we remove the tile, replace the underlayment with a synthetic high-heat product rated for tile roofs, and re-lay the salvaged tile. Homeowners are often surprised how much tile is reusable.
• Boral Saxony flat tile with cracked edges from foot traffic. Flat profile tile like Saxony shows cracks right at the tile edges where roofers or HVAC techs have stepped. A single cracked tile is a repair. When you’ve got cracks scattered across three or more slopes, that’s a sign the whole field is brittle from age and thermal cycling. That’s the point where replacement costs less over time than chasing individual tiles.
• Boral Villa cap and trim failures at hips and ridges. The ridge and hip cap tiles take the most direct sun and the most movement. We see the mortar or foam adhesive under Boral Villa cap tiles degrade and let water in along the ridge line. Water runs down the framing, stains the ceiling, and never shows up where the tile is loose. On replacement, we mechanically fasten every cap tile with stainless hardware and fresh adhesive, which is what the original install often skipped.
• Boral Mission S-tile with broken side locks from seismic movement. Los Angeles shakes. Mission S-tile interlocks along the sides, and after enough small earthquakes and thermal cycles, those locks snap. You get tiles that lift in the wind or slide out of place. It’s not a tile defect. It’s the roof moving as the house settles. We address this by checking rafter ties and adding fasteners per current seismic code before the new field goes down.
• Undersized or rusted flashing at valleys and penetrations. This is the one we see on nearly every older Boral roof in Los Angeles, regardless of tile profile. The tile was installed well, but the valley metal was too narrow for the pitch, or the pipe boots have corroded. Water backs up under the tile during heavy winter rain and finds its way inside. On every replacement we pull all flashing and install new, wider valley metal and lead-free pipe boots before the tile goes back.

Our Boral Roof Replacement Process

Here’s how a Boral replacement goes with us, from the first phone call to the last tile. It’s the same process Greg Holloway has run on hundreds of Los Angeles roofs.

1. 1
   Call and inspection. You call (945) 303-9821, a live person answers, and we schedule a site visit. Greg walks the roof, checks the attic, and takes photos. You get a straight read on what’s failing and what needs to change.
2. 2
   Written line-item estimate. Before any work starts, you get the full number in writing. Tile profile, underlayment type, decking replacement (if needed), flashing, haul-away, and the guarantee. No allowances for surprises that later become change orders.
3. 3
   Material selection and order. We match your existing Boral tile profile and color. If the color been discontinued, we’ll show you current Boral options or matching profiles from our other lines. We order from local Los Angeles supply yards to keep lead times short.
4. 4
   Tear-off and deck inspection. We strip the old tile and felt, then inspect the plywood or plank decking. Any rotted or delaminated sections get replaced before anything else goes down.
5. 5
   New underlayment, flashing, and tile. Synthetic high-heat underlayment goes down first, then new flashing at every valley, wall, and penetration. Salvaged tile goes back up along with new tile where needed, all fastened to current code.
6. 6
   Cleanup, inspection, and written guarantee. We run a magnet over the yard for nails, clear every piece of debris, and walk the roof with you. Before the crew leaves, you get the written guarantee. If anything fails inside the guarantee period, we return at no charge under the 365-Day Done Right Promise.

What Boral Roof Replacement Costs in Los Angeles

Boral roof replacement in Los Angeles runs on square footage, but what’s under the tile matters just as much as the tile itself. Here are the ranges we quote most often in this market. These numbers reflect 2025 pricing for this city, not national averages.

• Full tear-off and replacement with salvaged Boral tile plus new underlayment: $18 to $24 per square foot. This is the most common job we do. We reuse your existing tile where it’s sound and replace the broken pieces.
• Full replacement with 100% new Boral tile: $24 to $32 per square foot. New tile, new underlayment, new flashing throughout. Choose this when the existing tile is too brittle to salvage or you want a fresh profile.
• Decking replacement: $2 to $4 per square foot on top of the base price, only if we find rot or structural damage. We always confirm before adding a dollar to the estimate.
• Flat sections (garage, patio cover, second story deck): $12 to $18 per square foot for a torch-down or modified bitumen system tied into the tile field.

What shifts the number: roof pitch and access, the Boral profile you’re matching, how much tile is salvageable, and whether you’re in a neighborhood with steep hillside access. We’ll give you the exact number in writing before any work begins. Call (945) 303-9821 for a free estimate. Know the price before the first tile moves.

Why Los Angeles Homeowners Call Tilehurst Roofing for Boral Work

Los Angeles homeowners call us because the alternative has already failed them once. They’ve had a roofer no-show, or change the price at the door, or patch a Boral roof that leaked again in three months. We don’t do any of that. Every job starts with a written price before any work starts, and every repair or replacement ends with a written guarantee delivered before the crew leaves.

We’re a Kingswell family roofing company, which means we run on the Kingswell Way: say the price before the work, show up in the window we gave, leave the place cleaner than we found it, put the guarantee in writing, and come back if it fails. That last part is the 365-Day Done Right Promise. If a Boral repair fails inside a full year, we return at no charge. Not prorated. Not argued.

And if the right answer for your roof isn’t actually Boral, we’ll tell you. We carry and install seven major manufacturer lines, including GAF, Owens Corning, CertainTeed, plus IKO, Atlas, Tamko, and Boral. You get the product that fits your home, not whatever is left in the truck.
